Trophic Niche Overlap between Invasive and Indigenous Fish in a Northwest Reservoir of China [PDF]

Water, 2021
The Kizil reservoir in the Tarim River basin is an important habitat for the native Schizothoracinae fish (including Aspiorhynchus laticeps, Schizothorax biddulphi, Schizothorax eurystomus, Schizothorax intermedius and Schizothorax barbatus). Unfortunately, these species are threatened by many exotic fish, such as Ctenopharyngodon idellus, Silurus ...

Trophic Links Between Birds of Prey and Their Preys and Their Competitors in Wetlands During Nesting Period

Пернатые хищники и их охрана, 2019
The article is dedicated to the analysis of trophic relations of large birds of prey and adaptive mechanisms they use to reduce interspecific trophic competition during the breeding period in wetlands in Northern Belarus. The study shows that during this

Trophic overlap in mobulid rays: insights from stable isotope analysis [PDF]

Marine Ecology Progress Series, 2017
Mobulid rays, a group of closely related filter-feeders, are threatened globally by bycatch and targeted fisheries.

Resource Partitioning among “Ancillary” Pelagic Fishes (Scomber spp., Trachurus spp.) in the Adriatic Sea

Biology, 2023
The Mediterranean is one of the most overfished seas of the world where mesopredators are severely threatened. The trophic strategies of four pelagic species that inhabit the Adriatic Sea (Scomber spp.

Stable Isotope Analysis of Juvenile White Sharks Inside a Nursery Area Reveals Foraging in Demersal-Inshore Habitats and Trophic Overlap With Sympatric Sharks

Frontiers in Marine Science, 2021
Knowledge about top predators’ trophic ecology is crucial for defining their role in ecosystems, understanding habitat preferences, characterizing life stage-specific feeding habits, and evaluating their interaction with fisheries.

Trophic niche overlap decreases in related mesocarnivore species

Oikos
In natural environments, competition between species is a crucial factor for the survival or demise of populations. Therefore, understanding the mechanisms that promote species coexistence is crucial in community and evolutionary ecology. The Phylogenetic Limiting to Similarity Hypothesis (PLSH) posits that closely related species should experience ...

Plasticity and overlap of trophic niches in tropical breeding Laridae

Marine Ecology Progress Series
Trophic ecology of seabirds in tropical regions remains poorly understood despite the large number of multispecies breeding colonies supported by these ecosystems. Here, we used the isotopic niche (δ15N and δ13C) of 5 Laridae species at 2 breeding areas in Cuba to analyze the plasticity and interspecific overlap of trophic niche determined from chick ...

Lizard assemblage from a sand dune habitat from southeastern Brazil: a niche overlap analysis

Anais da Academia Brasileira de Ciências, 2016
Communities are structured by interactions of historical and ecological factors, which influence the use of different resources in time and space. We acquired data on time of activity, microhabitat use and diet of a lizard assemblage from a sand dune ...

Environmental factors drive trophic dynamics but not niche overlap of sympatric Lebiasinidae fishes in Amazonian streams

Neotropical Ichthyology
This study investigated the influence of environmental factors on trophic characteristics and interactions between two sympatric, phylogenetically related fish species, Copella arnoldi and Pyrrhulina capim, in Eastern Amazon streams.
